Txhawm rau saib xyuas kev sib txuas hauv network, xws li kev txheeb xyuas tus neeg siv online coj tus cwj pwm, kev saib xyuas kev khiav tsheb tsis zoo, thiab kev saib xyuas cov ntawv thov hauv network, koj yuav tsum sau cov tsheb khiav hauv lub network. Kev ntes cov tsheb khiav hauv network yuav tsis raug. Qhov tseeb, koj yuav tsum tau luam cov kev khiav tsheb hauv network tam sim no thiab xa mus rau cov cuab yeej saib xyuas. Network splitter, tseem hu ua Network TAP. Nws tsuas yog ua txoj haujlwm no xwb. Cia peb saib lub ntsiab lus ntawm Network TAP:
I. Ib tug Network Tap yog ib qho cuab yeej kho vajtse uas muab txoj hauv kev los saib xyuas cov ntaub ntawv ntws hla lub computer network.(los ntawm wikipedia)
II. ANetwork Kais, tseem hu ua Test Access Port, yog ib lub cuab yeej kho vajtse uas txuas ncaj qha rau hauv Network cable thiab xa ib qho kev sib txuas lus Network mus rau lwm yam khoom siv. Network splitters feem ntau yog siv nyob rau hauv network intrusion detection systems (IPS), network detectors, thiab profilers. Replicating kev sib txuas lus rau network li tam sim no feem ntau ua los ntawm ib tug switching chaw nres nkoj analyzer (span chaw nres nkoj), kuj hu ua chaw nres nkoj mirroring nyob rau hauv lub network switching.
III. Network Kais yog siv los tsim cov chaw nres nkoj mus tas li rau kev saib xyuas passive. Ib tug kais, lossis Test Access Chaw nres nkoj, tuaj yeem teeb tsa ntawm ob qho khoom siv network, xws li keyboards, routers thiab firewalls. Nws tuaj yeem ua haujlwm raws li qhov chaw nkag mus rau kev saib xyuas cov cuab yeej siv los sau cov ntaub ntawv hauv kab, suav nrog Kev Tshawb Fawb Txog Kev Tshawb Fawb, Kev Tiv Thaiv Kev Tiv Thaiv Kev Tshaj Tawm tau siv rau hauv hom passive, kev soj ntsuam raws tu qauv thiab cov cuab yeej saib xyuas tej thaj chaw deb. (los ntawm NetOptics).
Los ntawm peb lub ntsiab lus saum toj no, peb tuaj yeem kos ob peb yam ntxwv ntawm Network TAP: kho vajtse, inline, pob tshab
Nov yog saib cov nta no:
1. Nws yog ib qho kev ywj pheej ntawm kev kho vajtse, thiab vim li no, nws tsis muaj kev cuam tshuam rau kev thauj khoom ntawm cov khoom siv network uas twb muaj lawm, uas muaj qhov zoo ntawm qhov chaw nres nkoj mirroring.
2. Nws yog ib qho khoom siv hauv kab. Yooj yim muab, nws yuav tsum tau txuas nrog lub network, uas tuaj yeem nkag siab. Txawm li cas los xij, qhov no kuj muaj qhov tsis zoo ntawm kev qhia txog qhov tsis ua haujlwm, thiab vim tias nws yog ib qho khoom siv hauv online, lub network tam sim no yuav tsum tau cuam tshuam rau lub sijhawm xa mus, nyob ntawm seb nws tau xa mus rau qhov twg.
3. Pob tshab yog hais txog tus taw tes rau lub network tam sim no. Nkag mus rau hauv tes hauj lwm tom qab shunt, lub network tam sim no rau tag nrho cov khoom siv, tsis muaj kev cuam tshuam, rau lawv yog pob tshab kiag li, tau kawg, nws kuj muaj lub network shunt xa tsheb mus saib xyuas cov cuab yeej, cov cuab yeej saib xyuas lub network yog pob tshab, nws yog raws li Yog tias koj nyob rau hauv ib qho kev nkag mus rau lub qhov hluav taws xob tshiab, rau lwm yam khoom siv uas twb muaj lawm, Tsis muaj dab tsi tshwm sim, suav nrog thaum kawg koj tshem cov cuab yeej thiab mam li nco dheev nco cov paj huam, "Yuav koj lub tes tsho thiab tsis yog huab"......
Ntau tus neeg paub txog qhov chaw nres nkoj mirroring. Yog lawm, chaw nres nkoj mirroring kuj tuaj yeem ua tiav cov txiaj ntsig zoo ib yam. Nov yog qhov kev sib piv ntawm Network Taps / Diverters thiab Port Mirroring:
1. Raws li qhov chaw nres nkoj ntawm qhov hloov pauv nws tus kheej yuav lim qee cov ntawv yuam kev thiab cov pob ntawv uas muaj qhov me me dhau, qhov chaw nres nkoj mirroring tsis tuaj yeem lav tias tag nrho cov tsheb tuaj yeem tau txais. Txawm li cas los xij, lub shunter ua kom muaj kev ncaj ncees ntawm cov ntaub ntawv vim tias nws yog "thim" tag nrho ntawm lub cev txheej.
2. Hais txog kev ua haujlwm ntawm lub sijhawm tiag tiag, ntawm qee qhov kev hloov pauv qis, qhov chaw nres nkoj mirroring yuav qhia txog kev ncua sijhawm thaum nws luam tawm cov tsheb mus rau mirroring ports, thiab nws kuj qhia txog kev qeeb thaum nws luam tawm 10/100m ports rau GIGA ports.
3. Chaw nres nkoj mirroring xav kom lub bandwidth ntawm qhov chaw nres nkoj mirrored ntau dua los yog sib npaug rau cov sum ntawm cov bandwidths ntawm tag nrho cov mirrored ports. Txawm li cas los xij, qhov kev xav tau no yuav tsis ua tau los ntawm txhua lub keyboards
4. Chaw nres nkoj mirroring yuav tsum tau teeb tsa ntawm qhov hloov. Thaum cov cheeb tsam yuav tsum tau saib xyuas yuav tsum tau kho, qhov hloov pauv yuav tsum tau kho dua tshiab.
